Description
Technical field
The present invention relates to a kind of precharging type syringe and sleeve, belong to the technical field of medicine equipment.
Background technology
Precharging type syringe is conventional medicine equipment, such as Chinese patent CN201080065717.4,
Disclosed in CN201080028000.2, CN200820027626.1, CN201310630705, it generally comprise sleeve, piston,
Protective cap and core bar, piston connect together in the cylinder of sleeve with core bar, by promoting core bar and then promoting piston pre-
The physiological saline filled in sleeve pipe or other solution release syringe and carry out flushing of pipeline.Precharging type syringe, its advantage is note
Liquid suction need not be carried out when penetrating, can directly be used, reduce the operating procedure of medical personnel, reduce cross-infection machine
Meeting.
Why precharging type syringe sells well had the advantage that in itself mainly due to product.Medical market becomes
Change, biotechnology therapy and be only capable of by the drug candidate increasing number of injection administration, the therapy field that they are related to
Widely, such as multiple sclerosis, infertile, osteoporosis, hepatitis, rheumatoid arthritis, cancer, anaemia and hemophilia.
Some biotech drugs need the frequent drug administration by injection of sufferers themselves, and they are benefited most deep from the facility of precharging type syringe,
Because precharging type syringe eliminates certain operations step, allow using faster, easier.
It is the real motive for promoting precharging type syringe development the need for patient.For at present, the use of venous detaining needle
Also widely, as disclosed in Chinese patent CN201410216802.6, venous detaining needle is also known as venous catheter needle, core
The building block of the heart include can be retained in it is endovascular softness conduit, and stainless steel guiding puncture nook closing member.When using
Conduit and nook closing member are punctured into Ink vessel transfusing together, after conduit fully enters blood vessel, nook closing member is withdrawn out, only soft conduit is stayed
Put in intravascular so as to carry out infusion treatment.Enter after the completion of transfusion, medical personnel need to use syringe to inject physiological saline
In the conduit, in case blood back carries out forming thrombus in the catheter.
In consideration of it, can in advance be closed with physiological saline in precharging type syringe, distinctive pre-filled washing pipe injection is formed
Device.A kind of new pre-filled flushing syringe is disclosed in Chinese patent 200880103854, is provided with the near-end of its core bar
One resistance cap, its effect be pre-filled flushing syringe will physiological saline inject conduit in realize that washing pipe terminates after, can be with
The female Luer of venous detaining needle is sealed up using the resistance cap.But this structure is designed with a very big technical problem,
When the washing pipe of medical personnel's technology venous detaining needle is acted, because the conduit of remaining needle is stay in patient endovascular, so
When washing pipe is carried out, the vascular pressure for feeding back that its core bar can be received is very big, therefore medical personnel rush again
Its technical movements is that a pine is pushed away to core bar one when pipe, further pushes away a pine, rather than the process that continuously exerts a force.Exist
During this, the hand of medical personnel makes the resistance cap for being pointed to core bar near-end constantly be exerted a force to put the action of power, and hinders bacterium
The outermost of cap is aluminium foil overlay film, and easily stress produces rupture or separated with the surface of resistance cap, thus brings one
The risk that liquid in resistance cap is contaminated and fails；Further, since the hand of medical personnel directly with the resistance bacterium with aluminium foil overlay film
Cap end contact, rather than the smooth force end surfaces of conventional core bar near-end, therefore the feel of medical personnel also can be poor.
